Some additions:

I did some digging in the docs about db2dj.ini:
It should have the correct entries for the informix server, since the
informix server was installed at time of instance creation/db2
installation.
But I got the same error messages with the informix server. That was what
made me install the informix client sdk...

By the way, I tested the informix server config with dbaccess to see if
everything is configured correctly on the informix side. What would you
suggest to use to test the configuration of the informix client (I found no
dbacces or anything else I could use for this)

Thanks again,
